Can anyone help me by providing a sample python-script to modify the size of anyone feature in this Blender model 3D model of Humanoid
As commented in your previous question (or dublicate), ManuelbastioniLAB  will probably suffice. You can change a lot of parameters in there, which you can also access via script.





To get information of how to access a certain parameter, just hover above it and press CTRL+C (if that doesn't work copy it by hand).

A short example of how you could change a parameter:

import bpy

def buttock_depth_Y(size):
    bpy.data.objects["f_ca01"].buttock_depth_Y = size
    bpy.ops.mbast.measures_apply()
    return

if __name__ == "__main__":
    buttock_depth_Y(9999)


To run the script either make a .py file with the code in it or do it in the scripting layout
